Split into partial fractions: 1 / ((x-1)(x-2))
Split into partial fractions: 1 / ((x-1)(x-2))
- A. 1/(x-2) - 1/(x-1)
- B. 1/(x-1) - 1/(x-2)
- C. 1/(x-1) + 1/(x-2)
- D. 2/(x-2) - 1/(x-1)
Answer: A) 1/(x-2) - 1/(x-1)
Explanation: 1/((x-1)(x-2)) = A/(x-1) + B/(x-2). A = 1/(1-2) = -1. B = 1/(2-1) = 1. So it is 1/(x-2) - 1/(x-1).
